Look at the Met Police crime map - it breaks 'East Dulwich' SE22 down into Wards (i.e. South Camberwell, Peckham Rye, East Dulwich, Village), and also breaks each of those SE22 wards into sub wards. It seems crime levels are low right across SE22. http://maps.met.police.uk/ (put SE22 into Search box) For distance to train station best use the map for guidance.
